Hi All,
I've been experimenting with Dynamic EMF for a while now (loving it),
and I am now trying to extend the Ecore Package itself dynamically.
What I would like to do:
1. Extend the EClass with an extra attribute (cid in this case, an extra
identifier besides 'name').
2. Create dynamic meta-models (like a Person class etc...)
3. Instantiate a person class, and being able to later get the EClass
its 'cid', like this:
short cid =
(Short)person.eClass().eGet(person.eClass().getEStructuralFe ature( "cid"));
This is what my code looks like for extending the Ecore model:
EAttribute cidAttribute = EcoreFactory.eINSTANCE.createEAttribute();
cidAttribute.setName("cid");
cidAttribute.setEType(EcorePackage.eINSTANCE.getEShort());
EcorePackage.eINSTANCE.getEClass().getEStructuralFeatures(). add(cidAttribute);
But this doesn't work, I think maybe because using
EcoreFactory.eINSTANCE will disable the extensability of the ECore
package already?
Thanks a lot in advance,
Ruben
